Downloaded from Accidents – Incidents Accident – – An occurrence in which any person on board the aircraft suffers death or serious injury, or in which the aircraft receives substantial damage Incident – – An occurrence other than an accident which affects the safety of operations

Downloaded from Poor Judgment Chain aka error chain Accidents and incidents rarely, if ever, are the result of a single cause Usually a series of errors occurs which lead to the accident or incident Break one link in the chain and sequence of events would be stopped

Downloaded from Communication When the rear-seat pilot of a dual-piloted T-33 aircraft attempted to adjust his position, he inadvertently deployed the life raft in the seat bucket survival kit. As the raft inflated, it pushed the stick forward, which caused the aircraft to pitch nose down. The front seat pilot attempted to correct the dive, but met resistance when he pulled the stick back.
Downloaded from Communication, continued Meanwhile, the back seater found and deployed the raft deflation tool. The front seater, trying to solve the control problem, heard an explosion as the cockpit filled with talcum powder from inside the raft, which looked very much like smoke. He identified the problem as an engine failure, closed the throttle and secured the engine.
Downloaded from Communication, continued As the haze cleared in the back, the back seater noticed the apparent engine flameout and ejected. The front seater then dead- sticked the aircraft into a field. Throughout this entire sequence, not a word was spoken.

Downloaded from ADM Works! United Flight 232 Captain Al Haynes – “We had 103 Years of flying experience in that cockpit... but not one minute of that 103 years had been spent operating an airplane the way we were trying to fly it. If we had not worked together, with everybody coming up with ideas and discussing what we should do next and how we were going to do it, I do not think we would have made it to Sioux City.”
